Can't run both AC's in Texas
I have a Fleetwood Excursion 2008. My power kicks off if I run. Both AC's. all power goes down. It is HOT in Texas. The coach is 40 foot and should really cool us. Some electrical parts work plugs...

To the OP... The previous poster (Dennis) and I both have Monaco products, and my HR is a few years younger than yours so we have some experience with your electrical system. Your coach has an EMS (Electrical Management System) so if operating properly, it will control your system very well.
The back AC (zone 2) is controlled off one leg of the 50 amp service, your front AC plus most of the other 120 volt items work off the other leg. To me, since both AC's work on the generator, you probably don't have a problem with the interior wiring. You may check your breakers and feel them noticing if any are particularly hotter than others.
Your coach uses standard, 1/2 size, breakers in your box available at any home improvement center for the majority of your electrical circuits. You can easily replace a breakers that appear to be hotter. On my rig, one of my breakers was running "hot" and was causing unusual problems with the coach. I replaced that breaker and all problems left. Guess what breaker that was? It was the hot water heater.
In hot weather, a general issue with RV Parks is a lowering of voltage throughout the park with everyone running AC's. Using an autoformer type of product, you can keep your voltage up, but you lose amperage doing so. Bottom line, without an autoformer, you are probably experiencing a drop in voltage that your EMS system is trying to handle.
I agree with Dennis' suggestions as to the possible cause of your problem and how to fix it.
